hawk, I'm out of town and doing this remotely, I don't have the pics uploaded. I'll get them to you when I get back (Sat. night or Sunday). The circuit board is about 6"x3" but cut into the shape of a control cavity. It says "SD" on it, perhaps Spector Design, and the bass it's out of is Korean.

No, I don't think so. I've had a couple of sets of these, and neither had a logo. Since they are "vintage" they have a vintage look. no logo, and the wire is cloth insulated. Just like the good-ole-days I guess.

Update: After a quick peek at the Basslines web site, I see the current model has a logo. I am not sure of the age of these pickups, but they aren't new. I do trust the guy I bought them from and like I said, it looks just like another set that I sold a few months ago. Could be the Seymour Duncan Antiquities I guess.

Historical note (lol) These pickups were owned by Lalo Garcia, the bassist now touring with Chuck Berry!
